Closer Examination

Looking straight at the Logitech G900 Chaos Spectrum, we can see that it has an aggressive look; I usually hate mice that don't stick to a standard shape since too many angles and strange contours tend to make mice look too tacky, but feel it has been done in a way that looks excellent, reminding me a little of a Lamborghini's front! The LMB and RMB buttons have a very nice, satisfying click that is a little louder than on some other mice I have used.


The left-hand side's contour is nice and allows you to use the two thumb buttons well while gripping the mouse comfortably. These buttons can be removed, which I will show you a little later on.


As you can see, the right-hand side mirrors the left; the G900 Chaos Spectrum is a completely ambidextrous mouse, which means both left- and right-handed people can use it without any problems. Even though the right-hand side has no buttons in this picture, there are buttons you can add.


Inside this small box are the USB dongle and extra buttons for the right-hand side, which allows you to add the buttons if you want. They are impressively easy to add; simply pull the blanking plate off and add the two new buttons. They are held on by magnets, and once attached, feel sturdy and have a nice clicky feel.


The omnidirectional scroll wheel is one I have had the pleasure to use; it can scroll forward and backward as per usual, but has quite a resistive feel to it, which isn't great when scrolling on websites. Logitech managed to combat this with a button situated directly behind the wheel - press it and the scroll wheel will spin freely with no resistance should you want to scroll through long documents quickly. The wheel can also be pressed down and can be moved to the left and right.


Just behind the scroll wheel and its button are two other buttons; these change the DPI at default, but can be reprogrammed to do anything you like.


The rear shows that the mouse is quite sleek, but there is plenty of width for a palm grip; again, you can see that it is the same on both sides, allowing for ambidextrous use.


Underneath the mouse are the on/off and sync buttons. I didn't have to use the sync button at all since the mouse worked straight out of the box, and I couldn't figure out how to make it lose connection so that I had to, which means I can't comment on it too much. The sensor used is the PMW 3366; it is exclusive to Logitech but is basically a PMW 3360, which is heralded as one of the best sensors on the market at the moment.


The cable for the Logitech G900 Chaos Spectrum is 1.8 meters long and has a soft, smooth sleeving on it that is quite silky to the touch. It didn't snag during the time I had with it, and when using the mouse in wired mode, it didn't add much weight. If you want to use the mouse wirelessly, you can plug the cable into the receiver using the adapter; this means that the cable does everything you need it to really, but the receiver doesn't need to be plugged in all the time.


You can plug the small USB dongle into your PC to then just use your wire to charge your mouse; you don't really need the adapter, but using it does free up a USB port and also makes the cable readily available.


The cable is essentially a micro USB cable with a rather strange pronged connector to make it fit into the mouse more securely.


Whilst the mouse is charging, you can see a charging indicator; this area is also RGB lit, and the color can be changed to suit your desires.
